Sandbox*
The Sandbox is an exploratory
learning space for extended
practice and review of acids &
bases.
• 14 Achievements
* Players must complete
Challenge Levels 1-2 before
unlocking the Sandbox.

Acids & Bases: Chemistry Connections
A conjugate acid is formed after a base accepts a proton.

Requires less‘Pull Energy’
Weak Acids Strong Acids
H2O is a weak acid.
The harder it is to remove a proton from an acid, the weaker the acid.
The easier it is to remove a proton from an acid, the stronger the acid.
CHEMISTRY CONCEPT: An acid can donate a proton to another substance. (Brønsted-Lowry)
CHEMISTRY CONCEPT: A base can accept a proton from another substance. (Brønsted-Lowry)
CHEMISTRY CONCEPT: Acid strength correlates to the ease in which a molecule can donate a proton. The Pull Energy Meter represents the ‘ease’ in which various acids are able to donate protons.
A conjugate base is formed after an acid donates a proton.
HI is a strong acid.
HCI H+ + CI-
COLLISIONS ® / ACIDS & BASES GAME GUIDE 6© 2017 PlayMada Games LLC. All rights reserved.
CHEMISTRY CONCEPT: Acid strength increases as atomic radius increases.
CHEMISTRY CONCEPT: The amount of ionization differs between strong and weak acids.
A strong acid completely ionizes in water.
A weak acid partially ionizes in water.

Acids & Bases: Chemistry Connections (cont.)
CHEMISTRY CONCEPT: A polyprotic acid can donate more than one proton to another substance.
CHEMISTRY CONCEPT: In a neutralization reaction, an acid and a base react to form water and an ionic salt.
HCI + NaOH H2O + Na+(aq) + CI-
(aq)
A polyprotic acid donates its 1st proton more easily than its 2nd proton.

Acids & Bases: Chemistry Connections (cont.)
CHEMISTRY CONCEPT: A substance that can act either as an acid or a base is amphoteric.
H2O can behave as an acid. H2O can behave as a base.
H2O is an amphoteric substance.
